NVIDIA releases GeForce GTX 780 for $649, claims more power with less fan noise

It's well over a year since the GTX 680 came out, but given how that card was a strong contender it may feel too early for an upgrade. NVIDIA knows the score, which is why it's made a particular point of pitching this year's card at owners of the GTX 580 instead. Upgraders from that GPU are pledged a 70 percent lift in performance, which is about double the gain a GTX 680 owner would see. On the other hand, something more people might notice -- if NVIDIA's slides prove to accurate -- is a 5dBA drop in noise pollution, as well new a approach to fan control that attracts less attention by varying revs less wildly in response to load. This is surprising given that most of the extra performance in this card stems from more transistors and greater power consumption, but that's what we're told. Feel free to hold out for our round-up of independent reviews or read past the break for further details.
